From 5b483747a92570176259bb896dcf2468291f3e42 Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Thu, 12 May 2016 07:06:11 -0700 Subject: [PATCH] drm/i915: Remove wm_config from dev_priv/intel_atomic_state We calculate the watermark config into intel_atomic_state and then save it into dev_priv, but never actually use it from there. This is left-over from some early ILK-style watermark programming designs that got changed over time.
